What does Fire Extinguisher C specifically target?

  1. Gasoline fires

  2. Oil fires

  3. Electrical fires

  4. Wood and cloth fires

The correct answer is: Electrical fires

Fire Extinguisher C is specifically designed to target electrical fires. These types of fires arise from live electrical equipment and can occur in various settings, including offices, factories, and homes. The extinguishing agents used in Class C fire extinguishers, such as carbon dioxide (CO2) or dry chemical agents, do not conduct electricity and are safe for use on electrical fires. Using the correct extinguisher is crucial, as water or other agents not designated for electrical hazards can create a risk of electrocution or further escalate the fire. Other classes of fire extinguishers target different types of fires; for example, Class A extinguishers handle ordinary combustible materials like wood and cloth, while Class B extinguishers are meant for flammable liquids such as gasoline and oil. Understanding the correct classification ensures safety when responding to a fire emergency.
